Frequently Asked Questions
Should I Block Linespider?
No, unless you want to remove your pages from that search engine. Linespider supplies its index, so blocking it can eliminate your visibility and organic traffic there. Nearly every website should allow this category. Almost none of the top websites we track currently have robots.txt rules for Linespider.
Does Linespider Follow Robots.txt Rules?
Yes. Linespider is expected to follow robots.txt directives, so a disallow rule is the appropriate first step. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether Linespider respects it.
Does Linespider Access Private Content?
No special access. Linespider can reach only content available to anonymous visitors and does not sign in. Make sure sensitive content is not public by mistake.
Why Is Linespider Visiting My Website?
Linespider is adding new or changed pages to its search index. It may have discovered your site through links, a sitemap, or direct submission.
How Can I Tell if Linespider Is Visiting My Website?
Agent Analytics tracks Linespider visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "Linespider". Look for recurring passes that revisit changed pages and discover new ones. Because Linespider does not publish a verification method, any client can claim its identity and a log match is only a clue.
